To all whom it may concern:

Be it known that I, RoMno J. Tnrcn, a citizen of the United States,residing at Eufaula, in the county of McIntosh, State of Oklahoma, haveinvented certain new and useful Improvements in Music-Leaf Turners; andI do hereby declare the following to be a full, clear, and eXactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to a music leaf turner and more particularly to anautomatic music leaf turning device.

The primary object of the invention is the provision of a music leafturner having spring actuated mechanism for automatically turningsuccessively music leaves and means for reversing said mechanism wherebythe previously turned music leaves will be reset.

Another object of the invention is the provision of a music leaf turnerwhich is adapted to be mounted at the front of a pianoforte and havingmechanism adapted to actuate music leaf supporting arms for turningmusic leaves connected to said arms said mechanism being controlled by amain winding spring, a manually operable lever to shift the mechanismwhereby the arms supporting the leaf music will be successively moved soas to turn one leaf after the other at the will of the operator andmeans for re setting the said mechanism.

With these and other objects in view the invention for example, consistsin the construction, combination and arrangement of parts as will behereinafter more fully de scribed and as illustrated in the accompanyingdrawings which disclose the preferred form of embodiment of theinvention. It is to be understood however, that changes, variations andmodifications may be made such as come properly within the scope of theclaims hereunto appended without departing from the spirit of theinvention.

In the drawings :Figure 1 is a front elevation of the invention. Fig. 2is a top plan view thereof. Fig. 3 is a longitudinal sectional viewthrough the casing to show the position of the interior mechanism. Fig.1 is a further top plan view with the top of the casing broken away.Fig. 5 is a vertical sectional view on the line 55 of Fig. 1. Fig. 6 isa further sectional View on the line 6-6 of Fig. 4t. Fig. 7 is a topplan view with the top of the casing removed showing the mechanismreversed. Fig. 8 is a plan view of the combined ratchet and cog gear.

Similar reference characters indicate cor- .responding parts throughoutthe several views in the drawings.

In the drawings, the numeral 10 designates generally the casing orhousing of the music leaf turner comprising a base plate 11, front andrear walls 12 and 13, end walls 11 and a top plate 15 upon which latterare mounted vertical spaced uprights 16 having upper and lower crossstrips 17 and 18 re spectively connected thereto and which form a backframe or rest for the music sheet.

Centrally in the top plate 15 and extending from the rear edge thereofis an open slot 19 with which alines a bearing groove 20 formed in thebottom or base plate 11 and mounted in the said groove and passingupwardly vertically through the open slot 19 is a rotary shaft 21 havingoutwardly proj ecting parallel upper and lower arms 22 to which issuitably connected at music sheet. Surrounding the said shaft 21 is ahollow shaft the same being cut away and having outwardly projectingparallel arms 2% to which is adapted to be connected a music sheet. Alsosurrounding the hollow shaft 53 is another hollow shaft 25 the samebeing cut away as at 26 to permit the movement of the arms 22 and 2%upon the rotation of the shaft carrying the same and which hollow shaft25 carries outwardly projecting supporting arms 27 to which is adaptedto be connected a music sheet.

Fixed to the lower end of the shaft 21 is a broad toothed cog gear orwheel 28 and to the shafts 23 and 25 are fixed toothed gears or cogwheels 28 and 29 respectively.

lVithin the casing 10 are rigidly mounted parallel plates or arms 29having pivotally connected thereto the ends of a U-shaped member 30 thesame supporting a'vertieally disposed key winding shaft 31 projectingupwardly through an elongated slot 32 formed in the top plate 15 of thecasing.

Fixed to the key winding shaft 31 is a winding drum to which isconnected one end of a main spring 3% the opposite end thereof connectedto a vertical pin or post 35 carried by the arms 29 and adjacent thewinding drum within the casing. Loosely mounted upon the winding shaft31 below the winding drum 33 is a cog gear 36 having formed in its upperface ratchet teeth 37 in engagement with a spring pawl 38 carried by thewinding drum and which pawl is adapted to ride over the ratchet teeth 37when the main spring is being wound upon the winding drum by the keywinding shaft and during the unwinding of the main spring the windingdrum 33 is locked to the cog gear or wheel 36 by the said pawl toautomatically turn the music sheet will be hereinafter more fullydescribed.

Pivotally connected to the U-shaped member 30 are links in the form offlat plates 39 which latter support a vertical short shaft L0 forming a.bearing shaft for a rotatable cog gear or wheel 11 meshing with the coggear or wheel 36 on the key winding shaft. Pivotally connected to thelinks 39 by engagement with the bearing shaft 40 are rocking plates thelatter fulcrumed as at 43 to the rigid arms 29 and carrying at theirfree ends a squared vertical shaft 4:4: having fixed thereto a cog gear45 and above the latter is slidably mounted on the said shaft 4 1 a gearwheel 46 the latter normally held contiguous with the cog gear 455 by atension spring t? and which gear to is adapted to be thrown into meshwith the gears 28, 28 and 29 respectively for rotating the same to causemovement to the arms supporting music sheets for turning the latter insuccessive order. Said cog gear so is provided on one side with a collarL8 engaged by a forked extremity 49 of a rocking lever 50 the latterpivoted as at 51 to a bearing 52 which latter is pivoted as at 52' to abracket 52* mounted on the bottom or base plate of the casing and whichlever is adapted to raise and lower the gear wheel 4:6 into engagementwith the gears 28, 2S and 29 fixed to the shafts carrying the armssupporting the music sheets. To look the rocking lever in its thrownposition there is provided a pivotal dog having an extension connectedto a rod 55 the latter connected to a spring controlled finger piece 55pivoted to the shifting lever. This finger piece 55 normally holds thedog in locking engagement with a notched post 56 during the shiftingmovement of the driving gears. Projecting outwardly from the U-shapedmember is an arm 56 carrying a set screw member 57 for locking amanually operable handle 58 in various adjusted positions and whichlever is adapted to be actuated by the operator for reversing the gearmechanism by bringing the cog wheel or gear ll into engagement with thecog gear 28 which will reset the arms supporting the music sheets afterbeing turned.

To connect the music sheets to the arms 22, 2 71: and 27 there areprovided clips 59. To maintain the shafts 21, 25 and 23 removablyconnected to the casing there are provided pivotal locking members 0whereby the said shafts can be easily withdrawn or detached from thecasing at the will of the operator.

To prevent the turning of the music sheets supported by the arms 22, 24;and 27 prior to being actuated by the leaf turnii'lg mechanism, there isprovided av spring controlled ,awl G1 which latter is pivoted as at (32to one end of an angular-shaped arm or piece (33 containing a curvedslot (l-lcentrally thereof in which works the shaft -l--lupon theshifting of the gear 45 (see Fig. (3) and this angular arm or piece (33is vertically slidable upon stationary posts or pins (35 so as to permitthe said locking pawl (31, to engage the teeth of the gears 28, and 2f)respectively should the shifting lever 50 be actuated to bring the gear1 A) in the plane of any one of the said gears 28, and 29 to meshtherewith for the subsequent turning of the music sheets.

In operation, presuming that the spring 34: has been wound and that thesupporting arms have been swung to the right of 'he axis of rotation ofthe shafts carrying the same and to these arms are connected the leavesof a music book and it now being desired to successively turn the leavesat predetermined intervals, the operator shifts the arm 56 to the rightto disengage the gear ll from the gear 28 and by this gear ll meshingwith the gears 36 and 4-5, which latter is fixed to the squared shaft4%, the same having slidably mounted thereon the gear 46 which at thismoment engages the gear so that by the action of the spring All, thesaid train of gears will rotate this gear 28, turning shaft 21 to theleft so as to turn the first leaf of the book of music in the samedirection. Now should it be desired to turn the second leaf of the bookof music, the operator actnates the finger piece 55 to release thepivotal rocking lever 50 and by pressing downwardly upon the same it iscaused to rock upon its pivot 52 and in this manner the gear if) israised into engagement with the gear 28 and by the action of the spring3- said gear 28 will turn or rotate the shaft 23, so as to turn themusic leaf connected to the supporting arms 24: to the left. lVhen it isdesired to turn the last or third leaf of the music book the rockinglever 50, is further depressed to raise the gear to, into engagementwith the gear 2t), and in this manner the said last or third leaf isturned to the left upon the rotation of the shaft 25, of the device.When it is necessary to shift the arms to the right the operator shiftsthe arm 56, to the left, which brings gear etl into mesh with gear 28and by the action of the spring 34- the shaft 21 will be caused to turnto the right and by the turning of the supporting arms 22 in thisdirection will effect the simultaneous turning of all of the other armsin the same direction.
